Descripción
SN 1988A is (with exception of the well-observed SN 1987A) the only type
II SN for which observations of the late tail of the light curve are
presently available. This SN showed a brief spike in the early visual
light curve followed by a long plateau lasting for about 3 months.
Spectra taken during both the plateau and the postplateau phases confirm
its being also a classical event of the type II-P class, very similar to
SN 1969L and SN 1986I. In this paper, the visual light curve up to 500
days after maximum is reconstructed, and the possible mechanisms that
can contribute to the very late luminosity are reviewed. Radioactive
decay of Co-56 seems to be the main contributor to very late luminosity.
